Application filed september 25, 1912. Serial No. 722,937.

To all whom it may concern:

- Be it known that I, CONSTANZE Burns, a citizen .of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Hand-Rubber, of which the following is a full, clear, and exact description.

-Among the principal objects which the present invention has in View are: to provide a rubber of the character described adapted to exert simultaneously 'a kneading and a rubbing action on the material being treated; to provide means for successively kneading the material being treated and for shifting the same intermediate the kneading members; and to improve the construction and arrangement of the rubber men-- tioned.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views, and in which- Figure 1 is a side elevationof a hand rubber constructed and arranged in accordance with the present invention; and Fig. 2

is a bottom plan View of the manipulating rollers.

. As seen in the accompanying drawings, the rollers 7 are mounted on opposite sides of the roller 8. The rollers 7 and 8 are each freely mounted to rotate, bearings being formed for the rollers by bending-wire arms 9, 9 and 10. The arms 9, 9 and 10 are rigidly held in a. frame 11, supported upon which is a handle 12. In the construction shown in the accompanying drawings, the frame 11 is constructed from a single strip of'metal bent to infold the arms 9, 9 and 10 in the manner shown invFig. 1 of the drawings. The ends of the strip forming the frame 11 are vertically disposed and united, to sup- The rollers 7, 7 and 8 difier in the surface formation. The rollers 7 are each rovided with a plurality of knobs 13. The obs 13 are arranged to form a number of annu- The rollers larly-disposed series, the various series being relatively parallel.

As contrasted with the surface configuration of the rollers 7, the roller 8 is provided with a spiral thread 14... The extent of projection of the knobs 13 and the thread 14 is varied to suit the character of work for which the rubber may be designed. If the rubber is intended for use in washing cloth, the height of the knobs 13 and the threads 14 is relatively great, whereas, if the rubber is used for washing or manipulating the human body, the knobs and threads are relatively slight. i

7 and 8 maybe constructed from any suitable material, that preferred by me being a suitable wood, rendered impervious to water. 7 7 When provided with a'tool of the character shown in the accompanying drawings and as above described, the operation of washing clothes is as follows: The cloth, when drawn from the bath or tub, is laid out flat upon a board or table, and the operator, grasping the handle 12 of the rubber, passes the rollers 7 and 8 more or less rapidly over the cloth. In the passage of the rubber over the cloth, the knobs 13 sink into the body of the cloth. The efiect ofthis movement is to produce a lateral stretching effect-upon the cloth between the rollers 7, 7. The cloth being moved laterally between the leading and following roller 7, the knobs 13 in the following roller avoid the indentations made 'or impressed by the leading roller. Thereby each particle of cloth passing under the rollers is kneaded by the knobs 13. Also, by the thread M, a rubbing action, which serves to aid in loosening the dirt particles from the surface of the cloth, is produced thereon.

When using the rubber for treatment of the human body, the knobs 13 elfect a ma- .-nipulation of the muscles below the skin,

while the thread 14 coincidentally therewith stretches the skinbetween and at the same time rubs the same. The double action of drawing or. smoothing the skin, while manipulatin the muscles, produces a much a frame connecting said rollers to provide desired e ect, Y parallel bearings therefor.

Having thus described my invention, I In testimony whereof I have signed my claim as new and desire to secure by Letname to this specification in the presence of 5 ters Patent two subscribing Witnesses.

A hand rubber, comprising a pair of CONSTANZE BITTER. spaced-apart rollers, provided with annu- Witnesses: larly-disposed knobs; an intermediateroller E; F. MURnocK,

having a spiral thread formed thereon; and PHILIP D. ROLLHAUS.
